Is Sisley Supremya worth 750 dollars

Sisley has always been an expensive brand, but even so my eyebrows shot up when I saw the $750 price tag of its latest potion, a night cream called Supremya. This king's ransom is justified, we are told, by the synergistic magic of all its botanicals. Well, let's see.

There are over 50 ingredients in Sisley Supremya and, of these, there are 13 botanical extracts and six botanical oils including bisabolol (essential oil of chamomile), plus shea. So, if I am going to be generous, about half of the ingredients are really earning their keep. The first extract, krameria triandra, does so in spades. It has a fine scientific pedigree as an antioxidant and is, according to one study, more effective than green tea or its most powerful component, epigallocatechin 3-gallate. It is also a good antibacterial and pesticide, which begs the question as to whether Sisley needed all the potentially irritating and toxic preservatives (five in all) it has thrown in. But I'll come back to that later.

Some of the other botanicals are Sisley favorites. You'll find padina pavonica and physalis in Sisley's Daily Line Reducer (a relative bargain at $470). Padina pavonica is an alga also known as peacock’s tail. It seems to have antioxidant properties although it is not the most powerful according studies comparing algae. Physalis has radical scavenging polyssacharides, according to one study. Sisley Supremya lists thallus extract. This is widely known as bladderwrack and is the brown seaweed you can find on beaches everywhere. Of it, the US National Library of Medicine has this to say: "there is a lack of high quality human studies available to support use as an antioxidant".

Cotton seed extract is somewhat unusual in cosmetics. Cotton seeds contain something called gossypol. This has recently been discovered to be an antioxidant. However, it is also a well known toxin that is prompting the development of GM seed that is gossypol free and can therefore be fed to cows. Shitake mushrooms (lentinus edodes) are also one of those frenemy ingredients. They have 40 times more ergothioneine, an antioxidant amino acid that occurs naturally in the body and is found in high concentrations around cells that are subjected to free radical damage, than wheat germ. However, the extract can also cause dermatitis.

The other 50% of the ingredients are typical cosmetic fillers and, while omitting parabens, Sisley has been content to use other preservatives that can have unpleasant side effects such as phenoxyethanol, sodium benzoate and chlorphenesin. Some research has also identified linalool and limoneme as carcinogenic.

Although krameria triandra is a standout ingredient and there are several other convincing antioxidants, Sisley Supremya wouldn't make it into our Five Best serums at any price.

the product is not worth the price 1] pick your parents 2] stay out of the sun 3]keep your face clean 4] use a good moisture creme and i cream 5] use buff puf at least once a day gentile

You Americans really do not understand the first thing about quality and efficacy in skincare. Sisley is a long established, family-owned company who develop, research and manufacture all of their products themselves, without outsourcing anything - unlike all the US 'beauty' companies that plague the market with their obscene rubbish masquerading as 'skincare'. You really have to appreciate the synergy between ingredients and the overall product formulation to even begin to understand the passion and quality of a company like Sisley. They're successful in a very demanding market, because they are passionate about formulating the very best products, and not just saturating an already crowded market with mediocre rubbish.

As a Nordstrom former employee, I can tell you that you can purchase these products at Nordstrom and you would never have had difficulty returning if there was a problem. Stop shopping at Saks people!

I have been using this product for a few days but I was shocked to find out the price. I love the texture and feel of it and will update after I have used it a month. Also, Stella it is not sax fifths policy it is Sisleys I know this because I have freelanced and worked for Sisley. They do not take back damages from stores. They truly believe their products are for the elite.

I wish I read your article before ruining my skin with this damaging product. I am also upset and disgusted with Saks Fifth Avenue's poor customer service and unethical business practice. At least Saks should contact Sisley for me to resolve this matter. Sak Fifth Avenue treated me with unbelievable disrespect.

Hi. Thank you so much for your informative article. I actually bought and used this supremya and had a bad reaction to my skin. My skin appeared more wrinkles and became uneven in skin tone and dark pigmentation became more apparent. I wanted to return to Saks Fifth Avenue within a week after I bought the product, and they refused to take it back and told me that there is something wrong with me. I contacted Sisley company and no response from that company.
